Reverse Engineering of Windows Distribution

[Markus Stenzel]

I have a Python software for Windows, packed into a single exe file and 
accompanied with a few dll and package files.

Is there any way to reverse engineer this packet by extracting the 
source files so they can be used on Linux/Unix? I have checked the exe 
but it seems to be compressed by zlib.

Some people on the mailing lists told my friend it's possible to get the 
code once you can "unpack" the files from the exe.

Anyone?
